Zoom lens and optical apparatus including the same |
| abstract |
Provided is a zoom lens in which a variation in aberration with respect to a temperature change is small and excellent optical characteristics can be easily obtained. The zoom lens includes multiple lens units in which a distance between adjacent ones of the multiple lens units changes for zooming. When an average value of a change in refractive index with respect to a temperature change within a temperature range of from 0° C. to 40° C. is ΔNav, at least one lens unit L of the multiple lens units includes multiple optical elements A made of materials satisfying a conditional expression: |ΔNav|>5.0×10 −5 . When an anomalous partial dispersion ratio for a g-line and an F-line is ΔθgF Δθ , at least one optical element A θ of the multiple optical elements A satisfies a conditional expression: |ΔθgF Δθ |>0.0272. |
